Patented Feb. '7, 1911. Serial No. 503,840.

Toall whom it may concern:

Be it known that I, EDWIN C. WAKELAND, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Key-Dulicating Machines, of which the following 18 a specification.

My invention 'rclatesjto that class of machines iordu Heating articles, in which the pattern artic e and lank from which the duplicate" .is' to be magic are separately clamped in a travelingcatriagc,-whereby the blank is held to s ifclrcorresponding contact with the cutting-,to'olas is permitted and defined by W My invention, tho h-apphcable for duplicating many artic e's,1s especially intended and adapted for'Iduplicating keys, particularly those for in-tumbler locks, and ionimonlyknown as ale-lock or cylindere s.

it has for its objectthe provision of a machine of this type, in which the several necessary movements and adjustments are provided for. by means capable of easy and simple manipulation, resu ting in speed and accuracy; and to this end my ingention consists in the novel constructions, p rrangements" and combinations which I can now fully describe by reference to.the accompanyingdrawmgs in Wh1' ch:

Figure 1 is a rear elevation of my machine. Fig. 2 is a plan of'the same. Fi 3 Fig. 4 is t e enlarged, of the pattern-key holder. Fig. 6

isa rear view of said holder. Fig. 7 is a de tail, enlarged, ofthe feet and intervening feed-nutof the carriage. Fig. 8 is a sectional detail of the gage.

1 is a bed to be suitably fastened down to a bench.

2, Figs. 1 and 2, isthe shaft-bracket, having a top bearing 3, in which the shaft 4 is journaled, said shaft having fitted to itsouter end a cleaner brush 5 and to its inner end a cutting-tool 6. This cutting tool may be of any suitable character; for the sake of illustration I have shown it as an ordinary milling wheel. It. is rcmovably mounted on the shaft, so that it may be taken off and replaced, or another substituted. The mountthe contact of a gage with the pat-' movably fitted to the shaft, say, for example, l

by screwing thereon. Upon shaft 4 1s a pulley 9 for the driving belt.

The shaft-bracket 2 is so mounted that it may be adjusted in two directions, namely, to swing to and from the work, and to .move laterally. Its lower end is carried by and is pivotally supported upon and between (1pposing pointed screws 10,- Fig. 1, which pass through lugs 11 rising from the bed, and said screws are fitted with nuts 12. By adjustin the screws, the. bracket may be move laterally; and it may swing on said screws. It is fixed in its swinging adjustment, by means of a screw pin 13 projecting from its side, said pin playing through a curved slot 1a in\ thelonger of the two lugs 11, and receiving a thumb nut 15 on its outer end, as seen 1n Fig. 3.

In the bed 1 is a socket 16, Fig. 4,'in which is adjustably fitted the base of the gage carrying pillar 17, said socket receiving a set screw 1-8 to fix the pillar in place, both with respect to its height and its movement on its axis. The head 19 of the pillar 17 is slotted at its inner end to seat and guide the gage 20, the stem 21 of said gage passing throughthe pillar head, as seen 1n Fig. 8, and thread-- ed to receive the adjusting nut 22 fitted upon it in a slot about midway of the head, as in Fig. i, and to also receive the setting nut 23 on its rear end.

24 is the carriage. It consists of a piece having separated feet 25 which are pivota'lly mounted upon a feed-screw 26, Fig. 1, said screw being mounted in'lugs 27 rismg from the bed. The feed screw is provided with a crank-handle 28 on one end. Between the separated pivotal feet 25 of the carriage is a nut 29, Figs; 1, 2 'and 7, having an arm 30 which is bolted. to an arm 31 of one of the feet 25, Fig. 7, so that said nut is practically part of the carriage. This nut is the feed nut and it is threaded upon the feed screw 26, whereby the latter has the function of moving the carriage in a line at right angles to the faces of the cutting tool and gage. This manner of mounting the carriage, not only aii'ords a most precise and accurate.

'the upper member key.

feed of said carriage, but also gives great; stability to t, as its separated feet prevent back, away from its work.

The upper part ot. the ca rriage is formed with two arms, 32 and 33, Fig. l. The arm 32 has passing through its top a short slide.

rod il-l, which is carried by the base member 3.3 oi the pattern-key holder, Fig. :3, so that said member may more laterally. This base member 35 carries an adjusting screw 36, Fig. (3, which is threaded through a nut 37 on the top of the arm 32. The disposition of these parts is such that by operating the screw 36 the holder of which the base member 35 forms a part may be moved laterally, in the line of the .t'eed of the carriage. The upper inner surface of the base member 35 is formed with a clamping ledge 37', Fig. 5, with which coaets the clamping face of 238 ot the pattern-lacy holder. This upper member ispirotally connected at. 3.) with an arm "t which is tinged to the upper part of the base-member at it, and thence extends outwardly to a thumbhold extremity A spring 43 is titted between this extremity 1+3 and an arm 4- extending outwardly t'roin the base member :35, and is arranged to keep the two members ot the holder normally together, with pressure sulticicnt to hold the pattern-key 4-5 between them, as seen in, Fig, 4. The pivoting ot' the upper membcrZBS ot the holder at 21ft, enables it to come down squarely on the The other arm It?) of the carriage has its top formed orln'm'ided with thebase-member "to ot' the key-blank holder, said member having the clamping ledge 18 upon which thelwy-blank l7 rests. See Fig. it. into the bitch ot the lmsc-anember it}. is screwed a handle 45) with a thumb-rest 50. Fig. It.

Between lugs :31. on the upper surface of the I base member 'ltl is pivoted the handle fr. ot'

the u )tl member 52) ot the her-blank l l p y 1 thecuttmg tool on the blank; a cut mg tool holder] The general operation ot' the nan chine in duplicating a key is the same as prior devices of thls type: that is to say. the

key-blank is led to the cutting tool in necessary cot-res mudence to the guidance and limitations of the gage acting upon the nregular edge ot the pattern key; but the special operations. which resultin speed and :n-curacy, and which are due to the novel constructions, adjustments, movements and manipulation ot' the machine, are now to be pointed out.

The clamping and releasing of both the pattern key and the. kcy-blank instead ot being etl'ccted by the operation of set screws,

which require time in their manipulation. are here etl'ected much more expet itlonsly. the releasing ot' both being by hand pressure,

and their clamping by a spring in one case turn the 't'eed screw in nitive the carriage.

l and by hand pressure in the other. The

same hand pressure which clamps the keyblank, holds the carriage up to its position tor work, wh le the.otherhand is free to This screw-feed of the carriage is more ac curate and ercn, than can follow the use of an ordinary lever to slide a carriage along upon guides. The adjustment of the pattern-key clamp by the screw 36 is easily and accurately et't'ected, and is for the purpose of setting 'it in the same distance ielation to the other clamp, as the gage bears to the hitting tool, so that the two keys may register. operating t'he'set screw l8'are those of turn ing the gage-carrying pillars 17 on its axis. and of determining its lieigh't, whereby the gage 20 may be set with great accuracy in these particulars, while the adjustment of the gage forward or baelc','by means of the nut 22, is made with facility, and speed, and accurately (lOtOlfllll'llt-S; its proper ahnement to the plane of the bitting'teeth.' The swinging adjustment ot the cutting-tool. bracket.

rendered possible by the thumb .ntlt .15 is to compensate for the wear on thetecth of said tool. When such wear takes place, the bracket. is swungtorward to carry the- :tool

to original position. WVere it. not so, the 9 teeth when worn would not cut square across the lngv-blanknbut would cut on a? bevel. The lateral adjustment of the-bracket is to accurately set the cutting tool in its distance relation to the gage. The-brush 5 is used to rcmme the bur tron! the finished duplicate.

Having thus described my invention what I claim as new and desireto secure by Letters latent is:--- c y ,i'
